MEANS Fon THE DAYLIGHT: LOADINGAND UNLOADING F PHOTOGRAPHIC sENsITIzED y PLATES.

Application filed-September 6, 1907. Serial N70."391',583.

To all whom it may concern:

Be it known that I, RUPERT RICHARD' ALLEN, a subject of t-he King of Great Britain, residing at Rubia Hotham street, East Melbourne., in the State of Victoria, Australia, clerk, have invented Means for the Daylight Loading and Unloading of Photographic Sensitized Plates, of which the following is a specification.

This invention has been devised in order to provide a simple and reliable means for loading and unloading sensitized lates for photographic pur )oses in the day ight and particularly for loading and unloading a number at a time, and operating same sequentially in the camera.

The means employed necessitates the packing of the plates (which have `an antiialation or other backing) in a special manner and the use of a novel plate-holder as hereafter referred to.

The invention is illustrated by the accompanying dra-wings whereof,-

Figure 1 is a longitudinal horizontal section through the plate-holder in its extended position, and Fig. 2 is a rear side elevation thereof. Fig. 3 is an end elevation of the plate-holder when closed. Fig. 4 is a fragmenta-ry sectional view showing a detail of Fig. 8. Fig. 5 is a vertical section through one part of. t-he plate-holder. Fig. 6 is a vertical section on line VI Fig. 1. Fig. 7 is a plan of a plate, and Fig. S an enlarged transverse sectionof a'portion thereof. Fig. 9 is an enlarged (broken) horizontal section through a packet of plates. Fig. 10v is an elevation of a )ortion of the packet. Fig. 11 is a horizontal section showing the mode of removing the exposed plates, and Fig. 12 is a similar `view of such plates packed after removal.

According to this invention each plate 1 has an anti-halation orother backing 2 provided with slightly thickened portions e raised strips 3 along two edges of the plate parallel with its line of travel to prevent the sensitized face being scratched or rubbed. This backing may be completely gummed or pasted on the plate or attached either' at one or both ends so as to be easily removed when developing.

The plates are packed with their sensitized faces foremost and not face to face as is customary in a specially constructed opaque cartridge 4, and the number of plates and Specification of Letters Patent.' y

i i l l size of the cartridge corresponds with the capacity ofthe plate-holder.

The cartridge 4 consists of a shallow box of wood, metal, cardboardor other suitable material formed with a longitudinal slot or open- PAtentd' Aug-4, 1908.

ing 5 in its bacl'g-while upon the front edges of three of its sides are formed undercut guides 6 adapted to receive the side edges and one end of an opaque detachable flexible cover 7 formed on or as an extension of said cartridge, and which passes in front of the sensitized face of the foremost plate and around. the out-let end of the cartridge and thence around the-back thereof where its end is secured or the whole cartridge held intact b a band. or thelike. This cartridge is placed in an opaqueenvelo i-sliaped wrapper 8 open at one end only an( one sideof said wrapper is preferably longer than the other and is guinrned on its\inte\rior edge. The package of plates made `u p-`}in the manner above described and :1s-shown in Fig. 9 is then in its marketable con( tion. v

The platefholder is formed in two parts 9, 10, adapted to be suitably conngcted together' either by a hinge 11 or otherwise, and one part 10 is arranged to receive tlekp'osed plates.

The part 9 of the plate-holder is formed 'with ribs 12, 12, to guide it intothe camera and is rovided with the usual slide 13 and with a ringed door 14 at the back having ab;

. The cartridge is then held in this position by hand or by the hinged door when closed, and its cover is removed by engaging the tab or end 16 thereof, and drawing same away from the cartridge when the sensitized face of the iirst lat-e is ready for exposure.

Vlrien the hinged door 14 of the plate-holder is closed and secured, its spring 15 passes through the slot or opening 5 in the back of the cartridge and presses the plates 1 forward into position.

The plate-holder is provided at its outlet` end with a slot 16 through which each plate after exposure is pushed by the slide.13, and said slot is normally closed to prevent .the

able' l i i intrusion of any actinic rays, by means of a spring shutter 17 or the like.

After the slide has been drawn out and the shutter of the camera operated and the plate exposed in the ordinary manner, the hinged' portion 10 of the holder is temporarily swung one part has an overlapping ledge 18 and a transverse vertical tongue 19, the latter being adapted tofit into corresponding groove 2() formed in the end of the other part 9. In

addition to this the. one part h'as two hori-` zontaltenons 21, 21, adapted to fit into corresponding mortises 22, 22, in the other part. By this arrangement the light is excluded from the top and bottom and sides of the joint..

The hinged or detachable portion 10 of the plate-holder is provided with a hinged door 23, and at its end approximate to the other part with springs 24, 24, which hold the plate stationary against the back of the holder and out ofthe line of travel of the next plate as it is pushed therein so preventing the jagging of the ends of said plates on one another. Furthermore it is provided with an internal sleeve 25 and also with an end slot 26 for the passage of the plate, which slot is normally closed by a spring shutter 27 or the like.

The envelop 8 in which the cartridge 4 was packed is placed in the hinged or detachable part'lO with its open end around the sleeve as shown inFigs. 1 and 6 and the door is then closed. "i,

The cartridge 4 at its forward side has an unobstructed opening through which the plat es are normally pressed by the spring 15, the exposure controlling slide 13 normallyT covering the foremost plate. IVhen the slide 13 is withdrawn to effect an exposure, the foremost plate will move forward under the action of said spring and will rest substantially in the plane of the slide 18, the innermost edge of the slide enga-ging the adjacent edge of the platex In order to transfer the exposed plate into the. envelopthe slide is pushed forward and the. end of the plate opens the shutters 17 and 27 and passes through the slot-s 16a and 26 and is dropped iito the envelop 8 into the position shown inl*` ig. 1 where it is heldby the spring 24 and when hinged the part 10 is conveniently swung back into the position shown by dotted lines 28 in' said ligure Where .it is locked, or if detachable it is simply disengaged from the other part. The next pla-teis then ready foi exposure and so on until thepartridge is exhaust-ed.

'hen itis desired to remove the exposed plates from the part 10 of the plate holder they are shaken downto the closed end of theV envelo and the latter is drawn slightly out of the tinged part as indicated bj. dotted 'A lines 29 in Fig; 1, and lthen turned back as shown in Fig. 11A end of'the envelop is closed' and heldin that position by the hand or the like and on being removed from the plate-holder is vfinally sealed by sticking the gtimincd edge 30 to the side of the envelop as shown in Fig. 12. The

exposed plates arf thus safely removed from,

the. holder without fear of fogging saine.

B v this means the open The slide 13 of the platejholder. has raised i strips 31 near its side edges to prevent the scratching of the plates, and is furthermore' provided "with longitudinal grooves 32 engaging studs on the plate-holder which limit its movements. l l Having now particularlyT described and ascertained the nature of my said invention and in what manner'the saine is to be performed, I declare that what I claim is 1.
